A: install java environment to ensure that java can call the correct
kafka Download: http://kafka.apache.org/downloads
Download and unzip kafka:
Two new folders for storing log data of zookeeper and kafka
Change setting:
1, the new zookeeper_data \ zookeeper folder to store the data of zookeeper
Edit config--zookeeper.properties of dataDir for the file you just created folder, clientPort default port number of the zookeeper
2, create a new folder for storing log data of kafka
Edit config--server.properties of log.dirs for the file you just created folder
Each start a kafka, broker.id must be unique, can not be repeated
Port number for the zookeeper
kafka the default port number is 9092
Message queue of step (basis having promoter sequence):
1, start zookeeper (running in the outer bin directory):
Linux / mac: bin / zookeeper-server-start.sh config / zookeeper.properties
Windows: bin \ Windiws \ ZooKeeper-Server-the start.bat config \ zookeeper.properties
2, start kafka (running in the outer bin directory):
Linux / mac: bin / kafka-server-start.sh config / the server.properties
Windows: bin \ Windows \ Kafka used to live-Server-the start.bat config \ the server.properties
3、创建topic，如名为test（在bin目录的外层运行）
linux/mac：bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
windows：bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
kafka也会有对应日志
zookeeper也有对应日志
4、列出topic （在bin目录的外层运行）
linux/mac：bin/kafka-topics.sh --list --zookeeper localhost:2181
windows：bin\windows\kafka-topics.bat --list --zookeeper localhost:2181
5、启动生产者发送消息 （在bin目录的外层运行）
linux/mac：bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
windows：bin\windows\kafka-console-producer.bat --broker-list localhost:9092 --topic test
6、启动消费者接收消息（可开多个），运行后会自动刷新消息 （在bin目录的外层运行）
linux/mac：bin/kafka-console-consumer.bat.sh --bootstrap-server localhost:9092 --topic test --from-beginning
windows：bin\windows\kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning
